Installed ML but Grey Screen At Reboot w/ GA-Z77X-UP5

Newbie here. I've tried following this guide: (Success!) GIGABYTE GA-Z77X-UP5 TH
As well as following this guide about UniBeast

Everything seems to work fine after running UniBeast but I get stuck on a grey screen when trying to reboot.

Components:

• GA Z77X-UP5 TH
• Intel Core i5-3570K Quad-Core Processor 3.4 GHz 4 Core LGA 1155
• EVGA GeForce GT 640 2048MB GDDR3

• Corsair Vengeance 16GB (2x8GB) DDR3 1600
• TP-Link 450Mbps Dual Band Wireless N PCI-E Adapter (TL-WDN4800)
• SanDisk Extreme SSD 240 GB SATA 6.0 Gb-s 2.5-Inch Solid State Drive
• Seagate Barracuda 7200.12 1 TB 7200RPM SATA 6Gb/s with NCQ 32MB Cache

I've tried installing on SSD then on Seagate HD with no change. I've tried changing the selections on Multibeast from what I've seen in other posts, but this is what I used most recently:


Here's some pics with verbose startup:

Try booting with -v GraphicsEnabler=No

Bingo. Thanks for your help.
